Delve into the greatest astronomical events

The Cincinnati Astronomical Society will review what it considers the top 12 astronomical events of all time.

At the next installment of the society's 2nd Saturdays program, society member Jack Berninger, a biologist and science educator, will present his list of 12 astronomical events that changed the history, geology and life on Earth.

Number one on the list might be the Big Bang that started it all, or the Chixculib asteroid that wiped out the dinosaurs 65 million years ago, Copernicus moving the sun to the center of our solar system, humans walking on the moon or one of NASA's most recent discoveries.

Bring your own list to compare.

Berninger will share the dynamics of the events and how they influenced our thinking and understanding of the universe, and how they continue to do so today.

The program begins at 8 p.m. Saturday, May 11, at the society, 5274 Zion Road, Cleves.

After the presentation, Astronomers will be on hand to answer all your spacey questions, you can tour the society's observatories and learn how telescopes work, and, depending on the weather, view Saturn and other night sky treasures through the society's four large telescopes.

Those who have their own telescopes are welcome to bring it along for expert help exploring the night sky.
